[gpfsug-discuss] gpfs performance monitoring

[Sven Oehme]

if you don't have the files you need to update to a newer version of the 
GPFS client software on the node.
they started shipping with 3.5.0.13
even you get the files you still wouldn't see many values as they never 
got exposed before. 

some more details are in a presentation i gave earlier this year which is 
archived in the list or here -->

Sorry to bother you again but dstat have some issues with the plugin: 

        [root at gss01a util]# dstat --gpfs 
        /usr/bin/dstat:1672: DeprecationWarning: os.popen3 is 
        deprecated.  Use the subprocess module. 
           pipes[cmd] = os.popen3(cmd, 't', 0) 
        Module dstat_gpfs failed to load. (global name 'select' is not 
        defined) 
        None of the stats you selected are available. 

I found this solution , but involve dstat recompile.... 

https://github.com/dagwieers/dstat/issues/44 

Are you aware about any easier solution (we use RHEL6.3) ? 


This worked for me the other day on a dev box I was poking at: 

# rm /usr/share/dstat/dstat_gpfsops* 

# cp /usr/lpp/mmfs/samples/util/dstat_gpfsops.py.dstat.0.7 
/usr/share/dstat/dstat_gpfsops.py 

# dstat --gpfsops 
/usr/bin/dstat:1672: DeprecationWarning: os.popen3 is deprecated.  Use the 
subprocess module. 
  pipes[cmd] = os.popen3(cmd, 't', 0)

NICE!! The only problem  is that the box seems lacking those python 
scripts:
ls /usr/lpp/mmfs/samples/util/
makefile  README  tsbackup  tsbackup.C  tsbackup.h  tsfindinode  
tsfindinode.c  tsgetusage  tsgetusage.c  tsinode  tsinode.c  tslistall  
tsreaddir  tsreaddir.c  tstimes  tstimes.c
Do you mind sending me those py files? They should be 3 as i see e gpfs 
options:  gpfs, gpfs-ops, gpfsops  (dunno what are the differences )

Regards,
Salvatore
